#627 of 717 2004 GMC Canyon 4x4 "Reduced Power" setting code P0601
Feb 06, 2012 (8:49 am)
I am new to the forums. My canyon started this saturday afternoon. Let it cool down drive a quarter mile and the same thing happens. Each time I cleared the code using OBDII and let it set. Eventually the canyon returned home powered by a flatbed with $190. The dealerships can't connect to the recall database provided by GM until 13 Feb. With two people who work and only one GMC running, I need help and/or advice.

I seem to be having the same issue with my '04 Canyon (2.8 4 cyl) as I am coming up on 85,000 miles. Some mornings it won't start, just starter grinds and grinds; I give up and take the other car. This morning truck did start, at lunch time did start to let me leave parking garage, 15 min later would NOT start after I had picked up lunch. Called AAA for tow, tried one last time 5 min after non-start and it DID fire up this time, took to dealership anyway. I had never got any amber check engine lights/codes.
They could not replicate problem, fuel pump pressure was good, fuel filter dirty enough to warrant changing. In all their fiddlin with it they got one code once (did they say crank sensor?). They took off an intake hose and shined light in to TBI and showed me carbon build-up at top, and while not claiming that was the root of problem, are recommending fuel injection system cleaning for a couple hundred bucks and I will probably authorize that. Someone online here mentioned AC connection to all this ... I do believe mine was off the first two times today when it stared, and that I had turned it on at mid-day before it did not start. This is where I am at this point.
#631 of 717 Been trying to get an estimate of repair coats
Feb 17, 2012 (7:22 am)
I'm new to this forum. My wife and I am retired so we don't have money to throw away. I went to a Chevy dealer to get an estimate for repairs on my 2006 Chevy Colorado 32,426 miles. I told them my check engine light was on. I also had it read at an auto parts store the Error codes were P0785 and P2610. They told me that I would have to pay $96.50 to have it checked out and had no idea what the problems were. It doesn't seem fair that since the truck has a module on it to tell what the problem is that I would have to spend $96.50 to get an estimate when the trouble codes are there. Seems like a rip-off to me just to get an estimate.

Well I understand how annoying this is, but in fact the trouble codes don't tell you which part is defective. No car computer can do that (yet). The trouble codes only tell us which system or circuit is in distress. So if say your trouble code was related to an 02 sensor, this doesn't mean the 02 sensor is bad...it just means something is making the 02 sensor read outside its normal range. Could be the 02 sensor, could be a bad fuel injector, could be a bad catalytic converter, could be a bad ignition coil.
So while I do agree with you that they shouldn't charge you $100 bucks just to READ the code, if they are charging you $100 to diagnose the actual problem--such as testing the 02 sensor, etc) and isolate the actual defective component, then that's fair enough.

I have not taken the truck to a dealer yet, San Diego County is outrageous with $108.00/hr for labor. I replaced the factory battery today; drove for 20 minutes straight with no check engine ligth or reduced power. I have not had any codes stored like the last time. Last code stored was P0606/ PCM. Has this fixed the reduced power? I dont have $1000 for a dealership to fix this.
San Diego GM dealership:
PCM: $410.00 , core $75.00
Labor for R&R of PCM: 1.5 hrs at $108.00/hr
and of course tax at 7.75%
